CDC isolated the virus and made it available for research. The press release from yesterday:
https://www.cdc.gov/coronavirus/2019...l-culture.html
The sequencing we have been using is from China isolating of the virus:

Therefore, we will see in the coming days if the China's sequencing was significantly different than what the CDC has. If it is then we have reasons for more sanctions, if it is not then we all should be good.
The fact that the vaccines from Pfizer and Moderna are effective 95%, can be an indicator that the sequencing we have from China is actually legit.
RNA and DNA sequencing has been around for decades, and it is a well understood and accurate technology at this point:

The novelty of this mRNA vaccine is the ability to preserve the sequenced messenger RNA for long enough to transport it long distances, and distribute it, and then inject it as a vaccine.
The risk is not the sequencing that much, but the other components they use to preserve it and bring it into your cells so the enzymes can do their job creating the proteins.
